PTC Resettable Fuses, also known as polymeric positive temperature coefficient (PPTC) devices, are becoming increasingly popular due to their unique characteristics such as protection against overheating, overload, high surge protection, low power consumption and easy installation. These fuses provide a safe, efficient and effective solution for a wide range of applications from automotive to medical. The B59870C0130A070 is a PTC Resettable Fuse with low inrush voltage, high peak current, and rapid response time.

Application Field: The B59870C0130A070 is designed for over current protection and over temperature protection in automotive, medical, industrial, domestic appliances and consumer electronic products. The fuse is primarily used to protect a variety of circuits, such as automotive battery systems, power protectors, back-up power systems, medical device safety, laptop/desktop computers, remote monitoring and control systems, multi-circuit protection devices, and many other applications.

Working Principle: PTC Resettable Fuses (B59870C0130A070) utilize a special patented memory metal design which provides a characteristic of self-resetting when the maintained current is exceeded. The device is composed of a positive temperature coefficient element (PPTC) and a positive electrode element. When the current passes through the PPTC element, the temperature rises sharply, which increases its resistance value. When the resistance value rises beyond a defined threshold, the PPTC element trips and cuts off the current flow. When the temperature drops and the resistance drops, the fuse will reset and allow the current to flow again.

When the B59870C0130A070 is used in an automotive application, it is designed to protect sensitive electronics from over-voltage, short circuit, overcurrent, and other fault conditions. In medical device applications, the fuse can provide protection against the effects of overcharging, short circuit, and other fault situations that could cause harm to the device or to a patient. Furthermore, the fuse features a low inrush voltage and a high peak current rating, which helps minimize risk of temperature rise in the event of an overload or fault situation. Additionally, the quick response time of the fuse is ideal for critical fault protection applications.

The B59870C0130A070 PTC Resettable Fuses are available in a variety of current ratings ranging from 5A to 20A, making it suitable for a wide range of applications. The fuses are UL recognized for their quality and safety performance, and come with a two-year warranty. With its versatility and reliable protection features, the B59870C0130A070 is an excellent choice for over current and over temperature protection.
